New York City had a large German section on the East Side between 79th to 86th and bordered by 2nd Avenue to Madison Avenue. And not just German food but Czech food too. I remember eating at a very good Czech restaurant in 1981 or 82 and having some delicious duck. I believe very few of these places are left. In their web site, http://www.heidelberg-nyc.com/#about, the Heidelberg Restaurant, which is still located in the heart of old Germantown, says that "Of the dozens of German restaurants that once adorned the streets of Yorkville in Manhattan's Upper East Side, the Heidelberg Restaurant is all that remains. Heidelberg has made it its mission to honor these establishments, and to preserve an important piece of cultural history."
